¨ The f-block elements are also known as inner transition elements and are located at the bottom of the periodic table. They include the lanthanide series (elements with atomic numbers 57 to 71) and the actinide series (elements with atomic numbers 89 to 103). The f-block elements have partially filled f-orbitals and exhibit a range of unique properties, including high reactivity, complex electron configurations, and the ability to form stable complexes.
